APPARATUS FOR IMPREGN'ATING AND nx'rmrc'rme mourns- FROM FABRICS.

. Application filed November 20, 1907. Serial No. 402,969.

To all whom it may concern: I Be it known that I, HARRY HEY, a subjectof the King of Great Britain, residing at Dewsbury, 1n the countyof.York,-'in the Kingdom of En land, chemist, have invented certain newan Relatin%)to Apparatus for Y 'Vashing,

rymg', or Extracting'Li uids from Fabrics and other Goods, for whicapplication has been made in Great Britain, No. 26,843, dated November26, 1906.

This invention relates to centrifugal machines, and especially toapparatus for carrying out the processes of impregnating, dryinganddextractlng liquids from fabrics and other goo s.

Amon theJobjects of my. invention are: to provi e an apparatus in whichthe goods ated with a volatile liquid or solvent an fluence' of avacuum; to provide an apparatus in which the hi h speed necessary can beobtained without anger tothe ap. aratus, and Without detracting from thee ects-required to arrange the door of the casing, in which the-cagerotates, in such a position that access can easily be'had and so thatthe tendencyof the centrifugal force set up by the rapid rotation willkeep the doors of the cage closed and thus avoid any twisting action;and to arrange the door of the casing so that it can be moved away quiteclear of the orifice which it closes.

In the accompanying drawings: Figure 1 shows a side v1ew of theapparatus as a whole; Fig. 2 is a detail plan view in partial the ca eatdiflerentspeeds.

section of the door of the casing. and its supports; Fig. 3 is an ee'v'ation' in partial section of half the cage removed from its casingand Fig, 4is an elevation showing half the casing and cage'in section,and'the gear for rotating In t e drawings, the casing a is supported inany-suitable manner and eld stationary, and contains a rotatable cage 6,haying a number of sector shaped; compartments 0.

end thereof away from the gearing hereinafter referred to, whilethedooi' e. of each compartment of the cage isar'ranged so as to .becapable of being brought.- opposite the door in the casing. These doorse are ar Y ranged with their hinges. ef between their mner edges and thecenter of the cage, so

that said doors will tend to close as the cage I rotates. Further, thehinges are arranged useful Im rovements in or Impregthen dried under theinright-angles to a diameter of the cage.

fare strengthening bands on the periphery so that the door-can turnabout a line at links 7' on the casing, and by means of the screwlc topress the door 11 against the casing, and; so hermetically close theorifice h. 1 represents the end of the casing and m strengthening ribsthereon.

n is a fast and loose pulley-device," the shaft of which carries aspur-wheel 0 which gears with a'further spur-wheel p, this spur-wheel pcarrying one'member'of a clutch q, carried osely on the shaft 1",journaled in the casing, the other member of which is carried bypulleys, fixed on shaft r, to which the cage is'fix'ed so as to journalin the casing. tie a suitable connection from the casing a tea suitablevacuum-pump u. and o represents, diagrammatically, a volatile vapor andair separating device interposed between the pump a and the casing.

The cage 1) is divided into the sector-she, ed compartments 0, for thepur ose of enab ing the fabric, or other goo dst0' e treated, to besubstantially uniformly distributed in the cage, this being importantsince in the rapid rotation of the cage, in the absenceof saidcompartments, the tendency would be to throw the work into a mass at onepoint in the circumference of the cage and thus unbalance and subjectthe apparatus to'irregular strains and render it liable to accident;also, the work in such mass. would not be.

thoroughly or properly impregnated and could not be properly andthoroughly; dried, nor the solvent expelled from the cage. Bydistributing the. work in com" partments of the cage, balance of thelatter is maintained,impregnation of the work becomes thorough anduniform, the work is quickly dried, and the solvent is completelyexpelled so that its recovery is complete: The periphery of the cage is,of course, foraminous, rendered so in this instance of my invention b ascriesof parallel cross-barsj" Wor orthesecured to t e'strengtheningbands and arranged slightlyseparated to permit-the solvent to properlyproperconditions of operation.

pass in. and out under the By arranging the doors e, of thecage-compartments c, at the side instead of on the periphery of thecage, the powerful centrifugal force cannot tend to cause them to fiyopen, but will tend tokeep them closed, this being a very importantfeature in my apparatus; and this arrangement of the doors e, incooperation with the arrangement of the door (1 inthe side of thecasing,enables the several compartments of the cage to be quickly and handilyfilled-through the casing. This, arrangement is rendered still moreeifective by hangin the door (1 of the casing remote from the ori ce71., as shown in Figs. 1 and 2, since the said door can be swung clearto one side away from any possibility of interference with the operationof filling the cage through the registering doors (1 and c. Thesevarious arrangements of parts add the important advantage to theapparatus of enabling it to be.

driven at much greater speed, because the cage and casln can be made ofmuch larger diameterand s orter axial length. This directlyresults inthe important function of economy in operation, since the cage mustalways be filled with solvent to a certain predetermined height and therecovery of the solvent is in direct proportion to the speed of theapparatus.

In operation, the goods are placed in the com artmentc of the cage 1),through the orifree in the casing, and the clutcharts g and 8 broughtinto engagement,so t at the pulleys 'n, which are rotated from anysource of power, will cause the rotation of the cage through thespur-wheels o and p at a slow speed. This slow speed of rotation of thecage is carried on until the goods are thoroughly impregnated with theliquid,-introduced into the casin then the clutch q is dis engaged andthe siaft 1' rotated directly from the source of power by means of thepulley s, whereb a high speed of rotation is setup. When t 's high speedof rotation is set up, the vacuum-pump a is also set in action, so thatthe casing a is placed under a vacuum and the centrifuging therein takesplace under vacuum, whereby the drying or extracting of the liquids fromthe goods is brought about not only by the centrifuging,

but also by the liquid being forced out of the goods, a casing having anorifice at one end, a

goods owing .to the vacuum set up.

I declare that what I claim is:

1. In apparatus for impregnating and drying or extracting liquids fromfabrics or other goods, a casing,-a door at the end of the easing, arotatin cage within the said .easing having a lura ity of compartments,doors on the end 0 the said cage arranged one for each com artment so asto register with the door of t e casing, and means for rotating thecage. v

2. Inapparatus for impregnating and drying or extracting liquids romfabrics or other bracket hinged on the said casing remote from saidorifice, a door on said hinged bracket corresponding to the orifice insaid casing, means for clamping saiddoor on the said casing, a rotatablecage within the said casing, doors at the end of said cage forregistering with the orifice of the casing, and means for rotating thecage.

3. In apparatus for impregnating and drying or extracting liquids fromfabrics or other goods, a casing having an orifice at the end, means forclosing the said orifice, a cage rotatable within the said casing,compartments in said cage, a door at the end of each of the saidcompartments, for registering with the orifice of the casing, hinged soas to turn about lines at right-angles to the diameter of the cage, andmeans for rotating said cage.
